Re: Cantor Confusion

David Marcus writes

Definition: A function f is continuous at a if lim_{x->a} f(x) = f(a).
For the function f(x) = sin(1/x), lim_{x->0} f(x) does not exist. So,
regardless of how we define f(0), f won't be continuous. That proves
that the discontinuity is essential.

Yes, thanks.
